Morphological similarities between DBM and a microeconomic model of sprawl
2010
JEL classification : C61; C63; D62; R21; R40; International audience; We present a model that simulates the growth of a metropolitan area on a 2D lattice. The model is dynamic and based on microeconomics. Households show preferences for nearby open spaces and neighbourhood density. They compete on the land market. They travel along a road network to access the CBD. A planner ensures the connectedness and maintenance of the road network. The spatial pattern of houses, green spaces and road network self-organises, emerging from agents individualistic decisions. We perform several simulations and vary residential preferences. Our results show morphologies and transition phases that are similar…
PCR testing for Treponema pallidum in paraffin-embedded skin biopsy specimens: test design and impact on the diagnosis of syphilis
2007
Background: Syphilis, a chronic infection caused by Treponema pallidum (T. pallidum), is a disease which is increasing in incidence, and thus more and more becoming a differential diagnosis in routine pathology. Aim: Since histological changes are not specific, we sought to develop a polymerase chain reaction (PCR)-based molecular assay for the detection of T. pallidum in formalin-fixed, paraffin-embedded tissues, and evaluate its diagnostic power, especially in comparison with other ancillary methods, i.e. immunohistochemistry and Dieterle staining. Methods: 36 skin biopsies with the clinical and /or serological diagnosis of syphilis were evaluated by morphology, immunohistochemistry and s…
Increased Expression of Integrin and Receptor Tyrosine Kinase Genes During Autograft Fusion in the SpongeGeodia cydonium
1999
Recently cDNAs coding for cell surface molecules have been isolated from sponges. The molecules for alpha-integrin, galectin, and receptor tyrosine kinase (RTK), obtained from the marine sponge, Geodia cydonium, have been described earlier. In the present study also the cDNA for one putative beta-integrin has been identified from G. cydonium. The deduced aa sequence comprises the characteristic signatures, found in other metazoan beta-integrin molecules; the estimated size is 95,215 Da. To obtain first insights into the molecular events which proceed during autograft fusion, the expressions of these genes were determined on transcriptional and translational level. The cDNAs as well as antib…
Apvērstā modeļa (Flipped classroom) principu izmantošana vācu valodas kā otrās svešvalodas nodarbībās vārdu krājuma apguvei un nostiprināšanai
2022
Diplomdarba tēma ir šāda: “Apvērstā modeļa (Flipped classroom) principu izmantošana vācu valodas kā otrās svešvalodas nodarbībās vārdu krājuma apguvei un nostiprināšanai". Diplomdarba mērķis ir izpētīt, kā apvērstā modeļa principus var izmantot vācu valodas nodarbībās pamatskolas 6. un 8. klasē vārdu krājuma bagātināšanai. Tiek pieņemts, ka, izmantojot apvērsto modeli klātienes mācībās un digitālos materiālus (video) patstāvīgai vārdu krājuma un gramatikas likumu atkārtošanai, izglītojamie var uzlabot savus mācību panākumus vārdu krājuma apguvē. Diplomdarba darba uzdevumi, kas kalpo mērķa sasniegšanai, ir šādi: teorētiskās literatūras un rakstu izpēte par attiecīgo tēmu, stundu plānu izstrā…

Darba autors: Sintija Smoļenska. Darba nosaukums: Pētnieciskās darbības prasmes sekmēšana dabaszinību nodarbībās 5 - 6 gadus veciem bērniem. Darba mērķis: izpētīt vecākā pirmsskolas vecuma bērnu pētnieciskās darbības sekmēšanas iespējas dabaszinībās. Kvalifikācijas darbā ir vispārīgi raksturota 5 – 6 gadīgu bērnu attīstība, izanalizētas pētnieciskās darbības veicināšanas iespējas pirmsskolā, kā arī apskatīta pētniecisko darbību prasmju sekmēšana vecākās pirmsskolas vecuma grupas bērniem dabas zinību nodarbībās, veicot pētījumu par pētniecisko prasmju attīstības iespējām praktiski darbojoties ar bērniem. Pētījuma rezultāti parāda, ka pētniecisko prasmju attīstības pieaugums starp sākotnējo u…
Synthetic environmental appraisal of waste management system: an application to the Sicilian region
2004
This paper addresses the problem of synthetically evaluating the environmental performances of urban solid waste systems. This, in fact, represents a crucial point in the management process of complex systems that local administrations are called to cope with, in order to provide decisions about policy options that involve different issues characterising the quality of life of people. Suitable methods of evaluation are clearly required for this aim. This work introduces the dashboard of sustainability and the ecological footprint approaches as aggregate indicators of the performances of solid waste management systems. The methods have been selected due to their intrinsic simplicities, provi…
Modeling crowd dynamics through coarse-grained data analysis
2018
International audience; Understanding and predicting the collective behaviour of crowds is essential to improve the efficiency of pedestrian flows in urban areas and minimize the risks of accidents at mass events. We advocate for the development of crowd traffic management systems, whereby observations of crowds can be coupled to fast and reliable models to produce rapid predictions of the crowd movement and eventually help crowd managers choose between tailored optimization strategies. Here, we propose a Bi-directional Macroscopic (BM) model as the core of such a system. Its key input is the fundamental diagram for bi-directional flows, i.e. the relation between the pedestrian fluxes and d…
BioTIME: A database of biodiversity time series for the Anthropocene
2018
Abstract Motivation The BioTIME database contains raw data on species identities and abundances in ecological assemblages through time. These data enable users to calculate temporal trends in biodiversity within and amongst assemblages using a broad range of metrics. BioTIME is being developed as a community-led open-source database of biodiversity time series. Our goal is to accelerate and facilitate quantitative analysis of temporal patterns of biodiversity in the Anthropocene. Main types of variables included The database contains 8,777,413 species abundance records, from assemblages consistently sampled for a minimum of 2 years, which need not necessarily be consecutive. In addition, th…

High Performance FOC for Induction Motors with Low Cost ATSAM3X8E Microcontroller
2018
In this paper the Authors present the Arduino Due board application for an induction motor field oriented control (FOC) algorithm. The low cost Arduino Due board is equipped with a ATSAM3X8E microcontroller that performs the algorithm calculation, data processing, current signals and speed/position data acquisition. The control algorithm has been developed with the help of the open source Arduino integrated development environment, whereas a user friendly control interface, used to manage the speed or position set point, has been developed in Java language by means of an other open source software, namely, Processing. An experimental test bed has been set up in order to validate the FOC sys…
